Question 1

messurment units for electric field potential (R) and electric field strenght (E)

Answer 1

R=V
E= V/m

Question 2

what is the expression (eqution) for the distance between the point of space and dipole?

Answer 2

¤=kpcos(¤) / E-r2)
where the small circle in the angle between the dipole axis and the line separating the given point?

Question 3

calculate the potential of the elctric field of dipole at distance of 10 cm from dipole perpendicular to the dipole axis (0-90grader) if its known that the dipole moment is equal to 0,2 cm and the medium permitiivity is 1 (the constant) 910^-9m2/C2

Answer 3

0 volt
formel ¤=kpcos(90)/r2

Question 4

how does the strengt E of the uniform electric field realte to the potential difference?

Answer 4

E=-Delta¤/deltas

Question 5

what are the messurment uniths for resistivity? (p)

Answer 5

p=Ω *m

Question 6

the resistivity characterizies?

Answer 6

the ability of a substance to conduct electric current

Question 7

how are interrelated R and resistivity p?

Answer 7

R=p*L/s
